    Measurement of methane, methanol and ethanol for the biomass monitoring for biofuels.

    The Series 8900 provides direct measurement of methane, methanol, and ethanol for the biofuel industry. The Series 8900 GC employs a flame ionization detector (FID). The methane, methanol, and ethanol in the gas sample are physically separated using proprietary GC columns. A dual-column configuration with timed backflush to vent is used to strip off moisture and heavier gases. At sample injection, a fixed volume of sample is carried through the pre-cut column. The backflush is timed so that primarily the MME and other similar compounds continue on to the analytical column. Contaminants are then backflushed to vent. Methane, methanol, and ethanol are separated from potentially interfering components on the analytical column and elute to the detector for analysis.

    Measurement of C1-C5 with carbon dioxide for oil & gas exploration.

    The PetroAlert Model 8900 combines the selectivity of gas chromatography with the sensitivity, broad dynamic range, and hydrocarbon selectivity of a flame ionization detector (FID) providing fast analysis of C1-C5 hydrocarbons and Carbon Dioxide required in Mud Logging for Oil & Gas exploration. The PetroAlert Model 8900 uses a dual column configuration with timed backflush to vent which is used to strip off moisture and C6+ hydrocarbons. A pre-cut column is used in series with the analytical column. At sample injection a fixed sample volume is carried to the pre-cut column. Backflush of the pre-cut column is timed from sample injection so that only C1-C5 hydrocarbons are eluted from the pre-cut column to the analytical column. C6+ hydrocarbons on the pre-cut column are then vented.

    Analysis of VOC compounds in water by Purge & Trap or dynamic headspace

    Context & Challenges Volatile organic compounds (VOC) can be dissolved in water. Sometimes water is polluted and to study contamination of VOC in finished drinking water, VOC must be measured. Chromatotec® Solutions Chromatotec® has developed a specific system for the measurement of VOC in water: a Purge & Trap system, the airmoPURGE. The analyzer is coupled with a degasing system allowing the extraction of dissolved gases. The complete system is based on: - 502.2 method from US EPA – “Volatile organic compounds in water by purge and trap capillary column gas chromatography with photoionization and electrolytic conductivity detectors in series – Revision 2.1”. - 524.2 method from US EPA – “Measurement of purgeable organic compounds in water by capillary column gas chromatography/mass spectrometry – Revision 4.0”.

    Ultraviolet disinfection systems for the de-ozonation industry

    Ozone is an allotropic form of oxygen; each molecule contains three atoms of oxygen instead of the usual two.  Ozone is a powerful disinfectant and has been used commercially for the treatment of potable water since 1904.  It is produced on site in the same way that ozone is formed naturally, by the discharge of electricity during a thunderstorm.  A high voltage is passed across a gas stream containing oxygen.  This method of ozone generation is called corona discharge.  The energy of the high voltage splits an oxygen molecule (02) into two oxygen atoms (0) - which recombine with ordinary molecules of oxygen (02) to form ozone (03).

  • Reduced Fat Interference with Analysis of Pesticides in Avocados

    QuEChERS (Quick, Easy, Cheap, Effective, Rugged, Safe) is a very popular method for the extraction and cleanup of fruit and vegetable samples for pesticide residue analysis.2-4 The extraction step uses acetonitrile and a salting out effect (with MgSO4). Cleanup is then accomplished using dispersive SPE (dSPE) followed by a centrifuge step prior to analysis. This application shows the clean-up and analysis using Supel™ QuE Z-Sep+ QuEChERS and an SLB®-5ms GC column.
